Sport Touring Muffler Install

When I bought my 700 it was completely stock. I dodn't really care for the stock muffler sound, looks, or how restrictive it is. I bought a HMF performance muffler form a forum member, but my PRM rack was in the way, plus it was way too loud for the area I live in, even with the quiet core.

I did some searching, and all the slip ons are over $200 for something that would be quiet and high quality. My buddy has a Yamaha FJR1300 sport touring bike, and after looking at the mufflers it has, I figured I could make one of those work. So I picked up a right hand FJR1300 muffler on Ebay for $25! They are 1300cc bikes and have 2 mufflers, so 650cc through each, right? Only way to see if it will work is to try it.

The plan: use the clamp section, and brackets from the old muffler to make the new muffler fit.





A little longer than stock, but about the same weight. Looks better too IMHO.



It does have a CAT, so it'll be interesting to see if that affects anything



Cut all the brackets off the stock muffler, mocked it up, then tack welded everything in place



Then took it off and welded everything securely



Masked off the muffler then painted all the welds, stock brackets, and stock piece of pipe



Then added heat wrap to the pipe section since the rest of the exhaust is also heat wrapped.





All bolted up and ready to be tested







The result: A lot better flow than stock, a lot quieter than stock, but with a really cool performance sound. I was able to take it out for a ride today and noticed a bit better response, low end torque, and maybe a little more top end. I have a short video, but need to upload it.

Just hadn't seen this done before, so I wanted to post it here and see what everyone thinks.

I think its a good thing you have that 6 pack rack. That silencer is long. It does look much better than the oem oil drum they used on these quads. Looking forward to hearing a sound clip.

I got it from this company:

http://www.prm-atv.com/index.php/hon.../trx700xx.html

It has a mount where you can re-locate the stock light below the rack, but I mounted my license plate there. I just added a LED trailer brake light on the rear of the rack(as you can see in the second to last picture).

Not bad... I like the look of it compared to the stock muffler. Just a question did you re-tune the engine after installing the muffler? How did it perform compared to its stock muffler?
